An exterior angle is created by extending one side and measuring the angle between that extension and an adjacent side. An irregular polygon is any polygon that is not a regular polygon it can have sides of any length and each interior angle can be any measure.

### The length of the sides can vary even within the same hexagon except when it comes to the regular hexagon in which all sides must have equal length.

**How many sides does a irregular hexagon have**. A regular hexagon is convex meaning that the points of the hexagon all point outward. Hexagons that have sides of unequal length can be referred to as arbitrary hexagons. A regular hexagon has.

In an irregular pentagon pentagon sides and angles can be different sizes. Hexagons don t have to have sides of equal length though. It has six equal interior angles each 120 120.

Heptagon sides must be straight and meet to form seven vertices that close in a space. Interior angles of 120 exterior angles of 60 area 1 5 3 s2 or approximately 2 5980762 s2 where s side length. It should come as no surprise that the hexagon also known as the 6 sided polygon has precisely six sides.

How many sides does a hexagon have. This is true for all hexagons since it is their defining feature. They can be convex or concave but all concave polygons are irregular since the interior angles cannot all be the same if you drew a polygon at random it would probably be irregular.

It also has six equal exterior angles. A triangle is a polygon with. All of the angles of a.

A regular hexagon has six sides that are all congruent or equal in measurement. The angles of a pentagon add up to 540 degrees. It has five sides and five angles all of which are the same length or size.

Any closed shape with six sides is a hexagon. Regular or irregular polygon. Or the sides can be congruent to form a regular heptagon.

A regular polygon must have all sides and angle equal an irregular polygon does not have to have all sides equal but some may be equal an irregular hexagon may have 2 3 4 or 5 equal sides. What are two attributes that we use to classify polygons. The shape on the left is a regular pentagon.

Regular hexagons have six sides of equal length and interior angles that add up to 720 degrees. The seven sides of a heptagon meet but do not intersect or cross over each other. As with other 2d shapes a heptagon s sides can be different lengths which creates an irregular heptagon.

Our hexagon has six congruent sides.
